IMPROVEMENT IN WAGON-SPRINGS.

Specification forming part of Letters Patent No. 133,15), dated November 19, 1872; antedated November 15, 1872,

To all 4whom 'it may concern:

Be it known that I, GnAUN-or HOLMES GUARD, of the city ofNew York, in the State of New York, United States, temporarily residing in the city of Toronto, Canada, have invented certain Improvements in Springs for NVagons, die., of which the followin gis a specitication:

My invention relates to an improved spring for wagons and other vehicles; and consists essentially in supporting the body of the ve- ,hicle on rubber balls held in cups properly constructed, which cups are attached to the said body by bolts either on a swing-joint or working in slots for the purpose hereafter described.

The drawing is a side elevation, onehalf being in section.

A, body of vehicle B, rubber balls; C, cup for holding balls; D, bolts; E, supports attached to axle-tree. The boltsD pass through oblong holes in the cups C, thereby permitting the supports E to sink and give in proportion to the weight carried on thebody A; for, it ri gidly bolted, no motion could be obtained. The same object mightbe secured by having a hookand-eye joint. It will be noticed that the top of the balls B lit into the body A, their bottoms resting in the cups C. It follows, therefore,

that the bottoms resting in the said cups move with them as they approach the center, while the top of the balls remain stationary in the body A, thus giving to the body A the necessary spring, keeping it in a horizontal position, (or nearly so,) and is the essential and principal feature I wish'to secure. As represented by drawing, there is a ball at each corner, making four in all; but, of course, I have no intention of confining myself to this number. Instead of two bolts on each cup, one may, in some cases, be made to answer; and instead of the supports E working on the axle-trees, as shown, an iron or steel bar bent into a suitable shape and attached rigidly to the cross-bar or axle-tree may be, with advantage, sometimes substituted.

I do not claim a rubber spring nor the coinbination of a rubber ball and cups, for I believe they have before been used; but

YVhat I claim as my invention is- Itestingthe rubber ball B on swinging joints, as described.
